Advice Needed – New LPFM & Live Sound

so, you will send cable from mixer and equipment into the processer which will be at the studio? and then you want to send the signal to the transmitter site via adobe flash player? from what i can see on flash player there isn't a way to route sound from breakaway.
heres an idea you might consider. mixer via cable into computer running edcast either winamp or stand alone using flac, if you can get one maybe a rasbury pie computer might be a better option? stream to breakaway computer at transmitter site using winamp and the livelink plugin. and again if you can get one, have your winamp at the transmitter site run on a rasbury pie computer and then use a cable from that to your breakaway processing computer. of course if you need to keep the processer at the studio, you can run edcast standalone and record from whatever pipeline you use as your out and stream to the rasbury pie at the transmitter site. so, mixer, cable, processer, stream via edcast, rasbury pie, cable, transmitter. hope that helps. of course others might have other suggestions on doing this

Sound Card
You guys have mentioned the Marian Trace Alpha, ESI Juli and Maya44.  Which would you recommend for our application?  We will be sending an MPX signal into the transmitter from the sound card.[/quote]
Get the Marian Trace Alpha if the computer it's going in has PCI slots and can run Windows XP Pro SP3 32bit.

Second Method (Audio Routing)
In some cases, if this is even possible, we would like to take audio from an Adobe Flash Player into Breakaway and then out as an MPX signal.  We have a method to send the audio over the Internet as a link to the Transmitter that uses the Adobe Flash Player.[/quote]
That will work. Just set Windows' default playback soundcard to be the input you're using for Breakaway Broadcast Processor and everything that outputs sound to the default soundcard will go into Breakaway. Remember to disable all of the system sounds of course.

The question here is I have read you guys have used some type of updated pipeline program, besides what is supplied with Breakaway, so what do you recommend to route audio from the Adobe Flash Player to Breakaway?  Is this even possible?[/quote]
Yes, you can update it by installing the latest Virtual Audio Cable which can be cheaply purchased here:

But you shouldn't need to do that in most cases. As far as I know, none of the problems experienced by users have happened with Windows XP SP3 32bit.

Can you give your recommendations on hardware (computer & soundcards) and any additional software that may be needed for this application?[/quote]
For your Breakaway Live setup, I can recommend any USB-based RME soundcard.

I also recommend a Lenovo ThinkPad T410 (but I'm about to have a T420 in my studio tomorrow, with Windows 7 Pro 64bit, and I'll certainly test the latencies of it, since I'm thinking about getting one too.) The T410 with good specs (a fast Sandy Bridge i5) can be picked up used on eBay, in the USA, for $75 with free shipping. Sometimes even cheaper. With Windows XP SP3 32bit, the latency is insanely low. It's a rock solid platform that's used for years on a show I've been engineering for … soon 10 years. We're running 48 sample latency across multiple ASIO connections, with time-coded vinyl, realtime mic processing, multiple back & forth to a digital mixer, and final show processing, and there's zero perceptible latency. Zero glitches. I'd also get an SSD for any laptop being considered that doesn't come with one. Not just because excessively loud bass can destroy a hard disk. 😉

We were thinking, if the systems could be built similar, then we could use the system for live sound as a backup if the computer failed at the transmitter site.[/quote]
You'd have to give up the portability of a laptop to do that of course. That said… have you heard of SuperMicro servers?

I can't recommend anything specifically, but I've administered several hundred SuperMicro servers in the past 15 years, and they became my favorite cheap & good low-density servers.
